Forecast models for Cape Town on August 30 show a daily minimum likely between 9–12 °C, with traders assigning roughly equal weight to 10 °C, 11 °C, and 16 °C+ outcomes because ensemble guidance diverges on overnight radiative cooling. Clear skies expected under a strengthening South Atlantic high, combined with light southeasterly winds and low dew points near 5–7 °C, favor efficient heat loss after sunset in this Mediterranean winter climate. Recent surface observations confirm dry conditions and temperatures already dipping into single digits at inland stations, while coastal moderation keeps most projections above 8 °C. Model spread around boundary-layer mixing and exact cloud timing maintains the tight clustering of probabilities near the historical August average low of roughly 8–10 °C.
